In general you will have a better understanding of what is going on
in your application if you stick to using transforms to scale &
rotate your views, rather than to move your views (i.e.
translation). It is fully supported to use translation, and
necessary for certain types of animation, but if your goal is to
move a view to the center of the screen (for example) then setting
the view's center to the center of the screen is a saner approach
than using the transform matrix to do it.
Hi David,
my understanding was that the OP wanted to do all three operations
concurrently. Of course, if he wants simply to move, then scale, and
then rotate, there are easier ways to accomplish that than to use
transforms.
